Have fun getting all the girls to level 50 and getting all the stuff, it's a grind but a lot of fun :-D If connection permits, you can find me usually in the online Shinobi dojo, gotta stay up on that survival leaderboard XD
Oh and avoid Japanese online rooms, they'll kick you half the time especially if you use one of the more broken characters, and in survival you better HOG up the grunts, the more you kill per wave the more points you get. I'll let you find out who the best character(s) for that mode is ;-)
The net code is fine, although it'll sometimes uncommonly lose connection which isn't bad since you can just reenter the room, and actually Katsuragi is pretty good online, Haruka is more useful in point battle however
Usually I hate character who molest others, especially girls who grope other girls, and I still don't like that about Kat, but she is still very awesome in a lot of things: her attitude, her sense of justice, her backstory. And I enjoy her voice a lot.
